Description

The present invention relates to compositions intended
for the treatment and protection of hair and containing, in a cosmetically acceptable medium, at least one ceramide and/or glycoceramide and one cationic polymer containing nitrogen atoms in the main chain.

The invention also relates to the cosmetic treatment process employing such compositions.

Hair-care formulations which make it possible to treat hair which has been damaged by inclement weather or by unsuitable hair treatments are already known in the prior art. Cationic polymers which have the advantage of improving these cosmetic
properties, inter alia, the disentangling and the softness of wet and dried hair, and also of protecting the hair fibers from these harmful agents, have already been used for this purpose. However, some cationic polymers have unsatisfactory
disentangling properties, and have a tendency, for example, when treatments are superposed, to make the hair lank and feel coarse.

Ceramides or glycoceramides which have already been combined with cholesterol esters for the purpose of protecting the hair fibre are also known. Application of these latter compositions or of ceramides alone to the hair result, however, in
cosmetic performance parameters which are inadequate, both on wet hair and on dried hair. The inventors have discovered that, surprisingly, the combination of ceramides or glycoceramides with certain cationic polymers results in especially advantageous
cosmetic properties, in particular as regards wet disentangling. In particular, the inventors found that the combination had a synergistic effect which is not simply the addition of the properties of the two components, in particular in non-detergent
media having a low or zero concentration of washing surfactants.

The inventors found that this effect was more especially obtained by combining ceramides or glycoceramides with cationic polymers containing primary, secondary or tertiary amine groups or quaternary ammonium groups in the main chain and having a
viscosity at a concentration of 1% by weight in water of less than 15 mPa.s.

In PCT Application WO 93/02656, the use was envisaged of cationic dispersions of ceramides or glycoceramides; the cationic surfactants used in such dispersions are, however, different from the cationic polymers employed according, to the
invention, and do not enable the desired effects to be obtained, inter alia they do not enable the fibers to be protected.

The present invention is therefore drawn to a non-washing composition intended for the treatment and protection of hair, based on ceramide and/or glycoceramide and on cationic polymers.

The present invention is also drawn to a process for the cosmetic treatment of hair, employing such a composition.

Other subjects of the invention will become apparent on reading the description and the examples which follow.

The composition intended for the treatment and protection of hair according to the invention is essentially characterized in that it contains, in a cosmetically acceptable medium, at least one ceramide and/or glycoceramide and at least one
cationic polymer containing nitrogen atoms in the main chain and whose viscosity at a concentration of 1% in water is less than or equal to 15 mPa.s, the composition containing less than 4% of anionic and/or amphoteric and/or zwitterionic surfactants.

The cationic polymers which are usable according to the invention are chosen from cationic polymers containing primary, secondary, tertiary or quaternary amine groups in the main polymer chain. They have a molecular weight greater than 500, and
preferably greater than 1,000. These polymers display, moreover, the viscosity properties defined above.

EXAMPLES

Example 1

The following composition was prepared:

______________________________________ Polyquaternium 2 (CTFA), sold 1 g AS under the name MIRAPOL A 15 Ceramide A 0.5 g APG 300, which is a (C.sub.9 /C.sub.10 /C.sub.11 alkyl) 2 g polyglycoside (1, 4), sold in aqueous solution containing
50% of active substance (AS) by the company HENKEL Hydroxyethylcellulose 0.5 g Water qs 100 9 pH adjusted to 7.5 with NaOH ______________________________________

Pressurization scheme: 90 g of composition

10 g Aerogaz 3-2

This composition formed a foam at the outlet of the aerosol device, which foam was applied to the hair and disappeared after being massaging in.

Examples 2A and 2B were not prepared according to the invention, but were comparative examples.

5 g of the compositions were applied to previously washed and rinsed locks weighing 2.5 g. The compositions were left in place for 5 minutes and the hair was then rinsed in running water. The disentangling of the wet hair was then evaluated.

It was found that the disentangling for the composition 2 was markedly superior to the disentangling obtained with the compositions 2A and 2B containing only either the ceramide or the cationic polymer.

Similar results were obtained using the following polymers in place of the polymer A: MIRAPOL A 15, MERQUAT 100, and a polycondensate of diethylenediamine and adipic acid crosslinked with epichlorohydrin, described in French Patent FR-2,252,840.
